In addition, pest species and species that impact on water quality are identified and examined. Funded jointly by the Sydney Catchment Authority and the Department of Environment and Climate Change, this work has arisen from the need to understand the fauna values within the Warragamba and Metropolitan water catchments (known as Special Areas), as well as the surrounding National Parks and Nature Reserves. Combined, these areas cover almost two thirds of the study area and almost 85% of the remaining native vegetation cover. Sydney is faced with the unusual situation of extremely high-conservation value bushland and water catchment lying adjacent to outer-suburbs. The contribution these protected areas make to conserve the distinctive fauna of the region cannot be overstated and without them many species would no longer persist. The fauna of the Greater Southern Sydney Region is both diverse and unique. The rugged sandstone landscape that fringes the city supports a highly characteristic suite of birds, mammals, reptiles and frogs. These include a number of nationally and state listed threatened species, some of which are endemic to these environments. These animals have adapted to utilise the immense areas of dry, scrubby woodlands and the towering sandstone cliffs with their myriad of caves, cracks and overhangs. Hidden within this inhospitable terrain, rivers have incised wide valleys where grassy, rolling plains are home to great mobs of kangaroos, Emus and threatened woodland birds. In stark contrast to this, in the deep, sheltered gullies and along the Illawarra escarpment, ancient subtropical rainforests abound with catbirds and fruit- eating pigeons. Meanwhile, on the highest peaks and subalpine plateaux, mean annual temperatures are much lower, snow occasionally falls, and an altogether different assemblage of animals is found. It is this great diversity of environments that leads to the fantastic variety of animals found in the region. This project has found 446 different species of terrestrial vertebrate fauna live in the Greater Southern Sydney Region. Over 600 systematic survey sites have been completed for most fauna groups. As a result 25 000 new fauna records have been entered on the DECC’s publicly accessible database - the Atlas of NSW Wildlife, including 1237 records of 63 different threatened fauna species. This enormous increase in knowledge about rare and threatened species in Greater Southern Sydney has allowed conservation priorities to be reset at a regional level. This exercise has shown that priorities for the conservation of threatened species in the Greater Southern Sydney Region are different to NSW-wide priorities. Some species, such as the Regent Honeyeater and Booroolong Frog were found to be exceedingly rare, in line with their State and Federal listings. However other species, some of which are secure elsewhere in NSW, warrant equal attention as they are close to local extinction; for example the Long-nosed Potoroo. Meanwhile, five species listed as Vulnerable under the NSW TSC Act (1995) – the Powerful Owl, Yellow-bellied Glider, Gang-gang Cockatoo, Glossy Black-cockatoo and Eastern Bentwing- bat, were found to be common and secure in the Greater Southern Sydney Region with few or no conservation efforts required in this Region to ensure their long-term survival. Four priority fauna habitats have also been identified: Grassy Box Woodlands, Upland Swamps, Alluvial Forests and Woodlands and Coastal Wetlands. These are habitat for the majority of priority fauna in the Region. Directing conservation efforts toward these environments will confer the greatest benefit to faunal biodiversity. These fauna habitats provide a focus for landscape level threatened species management such as pest, weed and fire management, land acquisition strategies, rehabilitation and revegetation work, and for the targeted mitigation of Key Threatening Processes. Further to this, major fauna corridors and linkages have been identified in the region, the conservation of which will aid in the long-term survival of nomadic and migratory species and animals with large home ranges, such as the Koala. For example, a corridor has been identified that links the cool highlands in the south-west of the region to the warmer Illawarra coast, providing a passageway for species that seasonally move between these environments and also affording the potential for species to adapt to human-induced climate change. Finally, vertebrate pest species and species that are thought to impact on water quality have been given special
